Abstract
A negative-pressure hydraulic turbine generator set is characterized in that cylindrical non-magnetic metal tubes (1) are hermitically arranged in a stator coil (9) an iron shell (7), an output cable (10) is connected with the iron shell (7). Compared with the prior hydraulic positive-pressure generators, the negative-pressure hydraulic turbine generator has the main differences that dynamic sealing assemblies which are easy to leak air and water are not used for a transmission shaft of the pressure hydraulic turbine generator set any more as the siphon current runs in the vacuum and negative-pressure status. The set adopts the non-magnetic metal tubes to absolutely isolate the stator coil from the water, three pairs of rare-earth magnetic tiles with opposite polarities are embedded in the hollow iron tube rotor to replace an excitation coil which is power-consuming and difficult to resist water and form a hydraulic turbine generator set integrated with generator and hydraulic turbine, thereby overcoming the difficulty in isolation of water and power and hidden danger of insulation, and solving the critical problems for the negative-pressure siphon hydraulic generation.
Description
Technical field
The utility model relates to a kind of negative pressure hydraulic generator unit, is used in particular for underground water siphon power field.
Background technique
Negative pressure hydraulic generator unit is different with at present common hydraulic generator unit, and its water wheels are operated in the negative pressure state.And the water wheels of existing hydroelectric power unit are operated in the water environment of positive pressure, the kinetic energy that the water hammer water wheels produce, by the motive sealing in the stuffing box rotating energy is transferred to the rotor of generator by mechanical axis, because any high-abrasive material is in long-term, high pressure, high speed rotating, wearing and tearing can appear unavoidably, cause water leakage phenomenon, but this can not influence the normal operation of positive pressure generator set.Yet in the generating of siphon negative pressure, the pipeline of syphonic water flow process all can cause hydraulic pressure unusual as gas leakage a little occurring, and siphon cutout, water wheels stall can not sent out electric fault.
Summary of the invention
The utility model negative pressure hydraulic generator unit does not have traditional motive sealing device, adopts no magnetic metal tube that the stator coil and the water of generator are tightly isolated.The rotor of traditional water turbine generator group all produces rotating magnetic field with exciting winding energising back, makes stator coil induction generating.Inside and outside whole immersions of underground water siphon negative pressure hydraulic generator unit, the generating set rotor has the rare earth magnetic shoe of three pairs of polarity opposed alignment to be fixed on iron pipe rotor outside formation, owing to adopt rare earth permanent-magnetic material to make the rotor magnetic source, replaced the expense electricity field coil of waterproof difficulty again.When impeller drives the permanent magnetic field rotation of rotor, can make stator coil induction generating equally.Because p-m rotor can not generate heat, do not have water power to isolate and the puzzlement of problems such as electric insulation yet, make negative pressure hydraulic generator unit can be in water environment safety, long-term, efficiently move.

Embodiment
In the accompanying drawing, siphon water enters from the right-hand member of no magnetic metal tube (1), and powerful syphonic water flow impact axial-flow wheel (2) drives hollow iron pipe rotor (3) and rotating shaft (4) is rotated together.Be embedded with the rotor high-speed rotation of three pairs of rare earth magnetic shoes (8), can make on the stator coil (9) and generate alternating current.。Rotating shaft (4) is arranged in the no magnetic metal tube (1), fixing hollow iron pipe rotor (3) in the rotating shaft (4), rotor (3) two ends are being fixed the axial-flow wheel (2) of coaxial rotation, rotating shaft is installed in the interior stainless steel bearing (6) of two spoke type supports (5), fixing three pairs of opposite polarity rare earth magnetic shoes (8) on the soft iron pipe rotor (3), no magnetic metal tube (1) is fixed on the inside of iron shell (7) and stator coil (9).The electric power that hydraulic turbine generator sends is drawn by output cable (10).The magnetic flux size of generated output size and magnetic shoe, the number of turn of stator coil, the water wheels rotating speed, the height of water, water flow all have substantial connection.Regulate and control generating output voltage and watt level, only need to regulate water flow and get final product.Between rotor of generator (3) and the stator coil (9), though have or not magnetic metal tube (1) to separate, magnetic gap is big slightly, because of rare earth magnetic shoe (8) has superpower magnetic force, so generating efficiency is still very high.
Claims (5)
1. a negative pressure hydraulic generator unit is characterized in that: cylindrical shape does not have the inside that magnetic metal tube (1) sealing is installed in stator coil (9) and iron shell (7), is connecting output cable (10) on the iron shell (7).
2. negative pressure hydraulic generator unit according to claim 1, it is characterized in that: cylindrical shape does not have two spoke type supports (5) is housed in the magnetic metal tube (1), stainless steel bearing (6) is housed respectively in two end supports, and rotating shaft (4) is installed in the inner ring of stainless steel bearing (6).
3. negative pressure hydraulic generator unit according to claim 1 is characterized in that: connecting hollow iron pipe rotor (3) in rotating shaft (4), an axial-flow wheel (2) of rotation is synchronously respectively adorned at its two ends.
4. negative pressure hydraulic generator unit according to claim 1 is characterized in that: cementation the rare earth magnetic shoe (8) of three pairs of magnetic opposed alignment on hollow iron pipe rotor (3) outside.
